You can also use a negative step in the slicing syntax for Python: Python In [7]: arr_2[:2:-1] Out[7]: array([6, 5, 4]) In this code, you are not specifying the start index of the slice, you are specifying the stop value should be index 2, and the step should be -...
However, one important distinction is that array slicing does not create views as flexible as NumPys. The following will not changeaas it would in Python. v=a[0, :]v[0]=100 Also, slices with steps or negative values are currently not supported (e.g.1:3:-2). ...

While using negative numbers works, it does a lousy job of explaining what is happening. Part of the problem is how many negative numbers are involved. Expanding out the formula, we get: 1 Assets - Liabilities = Investment + Revenue - Expenses - COGS With a little algebra, I can test fo...
In makefile terms this creates a new target in the following form: OUTPUT: MAIN_DEPENDENCY DEPENDS COMMAND If more than one command is specified they will be exe- cuted in order. The optional ARGS argument is for back- ward compatibility and will be ignored. cmake 2.8.6 Last change: ...
Standardization of a dataset is a common requirement for many machine learning estimators. Typically this is done by removing the mean and scaling to unit variance. However, outliers can often influence the sample mean / variance in a negative way. In such cases, the median and the interquartil...
